US EPA announces Significant New Use Rules for 23 substances

The United States Environmental Protection Agency (EPA) has issued significant new use rules for 23 substances. The rule includes nine Premanufacturing Notice (PMN) substances that are subject to consent orders under TSCA section 5(e) where the agency determined unreasonable risks are posed to human health or the environment. For the remaining substances, although EPA deemed their use posed no risk, it is concerned that deviation from the use scenario in the PMN might result in risks. The substances include: Polyether ester acid compound with a polyamine amide; Alkanenitrile, bis(cyanoalkyl)amino; Phosphonic acid ester; Fluorinated dialkyl ketone; Iron(1+), chloro[rel-1,5-dimethyl (1R,2S,4R,5S)- 9,9-dihydroxy-3-methyl-2,4-di(2-pyridinyl-.kappa.N)-7-[(2-pyridinyl-.kappa.N)methyl]-3,7-diazabicyclo[3.3.1]nonane-1,5-dicarboxylate-.kappa.N3,.kappa.N7]-, chloride (1:1); 3H-indolium, 2-[2-[3-[2-(1,3-dihydro-1,3,3-trimethyl-2H-indol-2-ylidene)ethylidene]-2-[(1-phenyl-1H-tetrazol-5-yl)thio]-1-cyclohexen-1-yl]ethenyl]-1,3, 3-trimethyl-, chloride (1:1); Brominated polyphenyl ether; Biphenyl alkyl morpholino ketone; 1,2-Cyclohexanedicarboxylic acid, 1-butyl 2-(phenylmethyl) ester; Tetrafluoroethylene chlorotrifluoroethylene copolymer; Fluoropolymers; Mercaptoalkoxysilane; Phenol, 2-[[[3-(1H-imidazol-1-yl)propyl]imino]phenylmethyl]-5-(octyloxy)-; Complex strontium aluminum, rare earth doped (five substances); Benzoic acid, 4-(1,1-dimethylethyl)-, methyl; Substituted alkylamides (two substances). The new rules require any intention to manufacture, import or process any of the substances to notify the EPA at least 90 days in advance. In addition, EPA has published notices of new substances submitted between 26 March and 6 April 2012. Further information is available at: Federal Register 25/4/12
